I use simple plane object with black material and put a point light above the plane. THe result is when using eevee , the light reflection is way to bright. (see the attachment : top image is cycle, bottom image is eevee). Is this my graphic card or any setting that i need to change ?
if you go into the settings of your light source you will see that the settings are different in EEVEE. changing the settings in EEVEE does not change how the light looks in cycles and vice versa. So you can tweak the settings to get the same ish result across render engines.
